CLAIMS:


1. A method for the autonomous drilling of ground holes by
a drill rig including a drilling arrangement, comprising
the step of: utilising an autonomous drilling procedure to
control the drilling arrangement to drill the hole on
locating the drill rig in a position where the hole is to
be drilled.

2. A method for the autonomous drilling of ground holes in
accordance with claim 1, wherein the drilling procedure
comprises the step of instructing the drilling arrangement
to drill in a manner which produces a collar around the
hole with debris from the hole.

3. A method for the autonomous drilling of ground holes in
accordance with claims 1 or 2, wherein the drilling
procedure further comprises the step of instructing the
drilling arrangement to flush the drill hole.

4. A method for the autonomous drilling of ground holes in
accordance with any one of the preceding claims, wherein
the drilling procedure further comprises the step of
instructing the drilling arrangement to stabilise the
inner walls of the hole.

5. A method for the autonomous drilling of ground holes in
accordance with any one of the preceding claims, wherein
the drilling procedure further comprises the step of
retracting the drilling arrangement from the ground hole.
6. A method for the autonomous drilling of ground holes in
accordance with claims 4 or 5, wherein the step of
stabilising the inner walls of the hole includes detecting
fallback in the hole, and where the amount of fallback
exceeds a pre-determined value, instructing the drilling
arrangement to repeat any one or more drilling procedures



-24-

in accordance with any one of claims 1 to 5.

7. A method for the autonomous drilling of ground holes in
accordance with any one of claims 2 to 6, wherein the step
of instructing the drilling arrangement to drill in a
manner which produces a collar around the hole with debris
from the hole comprises instructions to repeatedly
penetrate and retract the drilling arrangement within the
hole.

8. A method for the autonomous drilling of ground holes in
accordance with any one of claims 3 to 7, wherein the step
of instructing the drilling arrangement to flush the drill
hole comprises instructions to increase the flow of
liquids from the drilling arrangement to the drill hole.
9. A method for the autonomous drilling of ground holes in
accordance with any one of claims 4 to 8, wherein the step
of instructing the drilling arrangement to stabilise the
inner walls of the hole comprises instructions to
repeatedly penetrate and retract the drilling arrangement
within the hole.

10. A system for autonomous drilling of ground holes by a
drill rig including a drilling arrangement, comprising:
- a processor arranged to process an autonomous drilling
procedure to control the drilling arrangement to drill the
hole upon locating the drill rig in a position where the
hole is to be drilled.

11. A system for the autonomous drilling of ground holes
in accordance with claim 10, wherein the drilling
procedure comprises a module arranged to instruct the
drilling arrangement to drill in a manner which produces a
collar around the hole with debris from the hole.

12. A system for the autonomous drilling of ground holes



-25-

in accordance with claims 10 or 11, wherein the drilling
procedure further comprises a module arranged to instruct
the drilling arrangement to flush the drill hole.

13. A system for the autonomous drilling of ground holes
in accordance with any one of claims 10 to 12, wherein the
drilling procedure further comprises a module arranged to
instruct the drilling arrangement to stabilise the inner
walls of the hole.

14. A system for the autonomous drilling of ground holes
in accordance with any one of claims 10 to 13, wherein the
drilling procedure further comprises a module arranged to
retract the drilling arrangement from the ground hole.

15. A system for the autonomous drilling of ground holes
in accordance with claims 13 or 14, wherein the module is
arranged to stabilise the inner walls of the hole includes
detecting fallback in the hole, and where the amount of
fallback exceeds a pre-determined value, instructing the
drilling arrangement to repeat any one or more drilling
procedures in accordance with any one of claims 10 to 14.
16. A system for the autonomous drilling of ground holes
in accordance with any one of claims 11 to 15, wherein the
module is arranged to instruct the drilling arrangement to
drill in a manner which produces a collar around the hole
with debris from the hole comprises instructions to
repeatedly penetrate and retract the drilling arrangement
within the hole.

17. A system for the autonomous drilling of ground holes
in accordance with any one of claims 12 to 16, wherein the
module is arranged to instruct the drilling arrangement to
flush the drill hole comprises instructions to increase
the flow of liquids from the drilling arrangement to the
drill hole.



-26-

18. A system for the autonomous drilling of ground holes
in accordance with any one of claims 13 to 17, wherein the
module is arranged to instruct the drilling arrangement to
stabilise the inner walls of the hole comprises
instructions to repeatedly penetrate and retract the
drilling arrangement within the hole.

19. A system for the autonomous drilling of ground holes
in accordance with any one of claims 10 to 18, wherein
statuses relating to the drilling arrangement are
monitored by a processor.

20. A system for the autonomous drilling of ground holes
in accordance with claim 19, wherein the statuses relating
to the drilling arrangement includes drill rotation speed,
rotation pressure, bit air pressure, pull down speed, pull
down pressure, depth sensor, air pressure, fluid flow rate
or any combination thereof.

21. A system for the autonomous drilling of ground holes
in accordance with any one of the claims 10 to 20, wherein
the processor selects steps to instruct the drilling
arrangement based on the statuses relating to at least one
of the drilling arrangement and/or at least one of the
statuses relating to the drill rig.

22. A system for the autonomous drilling of ground holes
in accordance with claim 21, wherein the processor
instructs the drilling arrangement to manoeuvre the
drilling arrangement relative to the desired location of
the ground hole.

23. A system for the autonomous drilling of ground holes
in accordance with claims 21 or 22, wherein the processor
instructs the drilling arrangement to vary the pull down
rate, the pull up rate, the rotation speed, the bit air



-27-

pressure or the liquid flow rate.
